Card type 3 gives the number of wave conditions to analyze and sum- 

 marizes general input information (Table 3) . For the example breakwater 

 (Fig. 3), 18 wave conditions with periods of 5, 10, and 20 seconds and 

 with heights that range from 0.1 to 2.0 meters, are analyzed. 



Card type 4 gives material characteristics, one card per material 

 and the first card should describe the armor material. The example 

 gives three materials (armor, underlayer, and core); diameter and poros- 

 ity of the materials are shown in Figure 3. 



Card type 5 is used to input the mean horizontal length of various 

 materials in various horizontal layers of the breakwater. A new hori- 

 zontal layer occurs when there is a change vertically in material type 

 or slope and the layer next to the seabed should be designated as "layer 

 number 1." In the case of the example breakwater, three horizontal layers
